V. Shivaani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With increasing digitization, the world is coming closer, not only in terms of informational flow but also in terms of capital flows. And micro-finance institutions (MFIs) have perfectly leveraged this digital world by resorting to the innovative digital social peer-to-peer (P2P) lending platforms, such as, Kiva. These digital P2P platforms bring together micro-borrowers and lenders from across the world. The main objective of this study is to understand the funding preferences of social investors primarily from developed countries (such as US, UK, Australia), lending money to borrowers from rural India at zero interest rates through Kiva. Further, the objective of this study is to increase awareness about such a platform among various MFIs engaged in providing micro-loans to those in need. The sample comprises of India based micro-loan applications posted by various MFIs on Kiva lending platform over the period Sept 2012-March 2016. Out of 7,359 loans, 256 loans failed to get funded by social investors. On an average a micro-loan with 30 days to expiry gets fully funded in 7,593 minutes or 5.27 days. 62% of the loans raised on Kiva are related to livelihood, 32.5% of the loans are for funding basic necessities and balance 5.5% loans are for funding education. 47% of the loan applications have more than one borrower; while, currency exchange risk is on the social lenders for 45% of the loans. Controlling for the loan amount and loan tenure, the analyses suggest that those loan applications where the number of borrowers is more than one have a lower chance of getting funded as compared to the loan applications made by a sole borrower. Such group applications also take more time to get funded. Further, loan application by a solo woman not only has a higher chance of getting funded but as such get funded faster. The results also suggest that those loan applications which are supported by an MFI that has a religious affiliation, not only have a lower chance of getting funded, but also take longer to get funded as compared to the loan applications posted by secular MFIs. The results do not support cross-border currency risk to be a factor in explaining the determinants of loan funding. Finally, analyses suggest that loans raised for the purpose of earning livelihood and education have a higher chance of getting funded and such loans get funded faster as compared to the loans applied for purposes related to basic necessities such a clothing, housing, food, health, and personal use. The results are robust to controls for ‘MFI dummy’ and ‘year dummy’. The key implication from this study is that global social investors tend to develop an emotional connect with single woman borrowers and consequently they get funded faster Hence, MFIs should look for alternative ways for funding loans whose purpose is to meet basic needs; while, more loans related to livelihood and education should be raised via digital platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=P2P%20lending" title="P2P lending">P2P lending</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20investing" title=" social investing"> social investing</a>, <a href="https://publications.waset.org/abstracts/search?q=fintech" title=" fintech"> fintech</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20inclusion" title=" financial inclusion"> financial inclusion</a> </p> <a href="https://publications.waset.org/abstracts/96354/global-digital-peer-to-peer-p2p-lending-platform-empowering-rural-india-determinants-of-funding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96354.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Optimization of Wear during Dry Sliding Wear of AISI 1042 Steel Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sukant%20Mehra">Sukant Mehra</a>, <a href="https://publications.waset.org/abstracts/search?q=Parth%20Gupta"> Parth Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Varun%20Arora"> Varun Arora</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarvoday%20Singh"> Sarvoday Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Kohli"> Amit Kohli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was emphasised on dry sliding wear behavior of AISI 1042 steel.

In this research, we propose a CNN-based architecture, USENet, designed to overcome these limitations. Leveraging two key techniques, our approach achieves superior performance on the VoxCeleb 1 Dataset without any pre-training. Firstly, we adopt a U-net-inspired design to extract features at multiple scales, empowering our model to capture speech characteristics effectively. Secondly, we introduce the squeeze and excitation block to enhance spatial feature learning. The proposed architecture showcases significant advancements in speaker identification, outperforming existing methods, and holds promise for future research in this domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-scale%20feature%20extraction" title="multi-scale feature extraction">multi-scale feature extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=squeeze%20and%20excitation" title=" squeeze and excitation"> squeeze and excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=VoxCeleb1%20speaker%20identification" title=" VoxCeleb1 speaker identification"> VoxCeleb1 speaker identification</a>, <a href="https://publications.waset.org/abstracts/search?q=mel-spectrograms" title=" mel-spectrograms"> mel-spectrograms</a>, <a href="https://publications.waset.org/abstracts/search?q=USENet" title=" USENet"> USENet</a> </p> <a href="https://publications.waset.org/abstracts/170441/use-net-se-block-enhanced-u-net-architecture-for-robust-speaker-identification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170441.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Effect of Process Parameters on Mechanical Properties of Friction Stir Welded Aluminium Alloy Joints Using Factorial Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh">Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Gill"> Ankur Gill</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh%20Kang"> Amardeep Singh Kang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work an effort has been made to study the influence of the welding parameters on tensile strength of friction stir welding of aluminum.

A major fraction of this literature considers a large number of parameters in order to devise management techniques. However, multiple such parameters do not directly affect the result, and incorporating these can make the analyses overly complicated. Most of the causes of supply chain inefficiencies are due to the interconnectedness and interdependencies in the structure, processes, and environment of the supply chains. The level of complexity varies across industries in terms of intensity and ease of management. After a review of the literature related to complexities in supply chains, the paper attempts to build a framework to study the relative significance of these complexities. This paper aims to identify critical complexities for the garment industry. Understanding and controlling these complexities open avenues for better supply chain management and also assist decision-makers in the garment industry in formulating risk mitigation strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complexity%20dimensions" title="complexity dimensions">complexity dimensions</a>, <a href="https://publications.waset.org/abstracts/search?q=garment%20industry" title=" garment industry"> garment industry</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20complexity" title=" supply chain complexity"> supply chain complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/131661/analysis-of-supply-chain-complexity-sub-dimensions-for-garment-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131661.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Dielectric Properties of Ternary Composite Based on Complex Perovskite Oxides Synthesized by Semi-Wet Route</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20D.%20Mandal">K.

The phase structure of the sample was identified by X-Ray diffraction. The micro structure of the sample was observed by SEM, which displays grains of different shapes having diameter in range of 2 µm–4 µm. We have studied the frequency and temperature dependence of permittivity and impedance of the compound with LCR Meter in the range of 100 Hz–1 MHz and 300–500 K. The material shows its highest dielectric constant (428000) at 100 Hz and 368 K. The material shows Debye–like relaxation and their dielectric constant are independent of frequency and temperature over a wide range. The sample shows two electrical responses in impedance formalism, indicating that there are two distinct contributions. We attribute them to grain and grain boundaries in the ceramic sample and explain the dielectric behaviors by Maxwell–Wagner relaxation arising at the interfaces between grain and their boundaries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20perovskite" title="complex perovskite">complex perovskite</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramics%20composite" title=" ceramics composite"> ceramics composite</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance%20study" title=" impedance study"> impedance study</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a> </p> <a href="https://publications.waset.org/abstracts/18525/dielectric-properties-of-ternary-composite-based-on-complex-perovskite-oxides-synthesized-by-semi-wet-route" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18525.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Carbon Dioxide Capture, Utilization, and Storage: Sequestration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Sachan">Ankur Sachan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon dioxide being the most anthropogenic greenhouse gas,it needs to be isolated from entering into atmosphere. Carbon capture and storage is process that captures CO2 emitted from various sources, separates it from other gases and stores it in a safe place preferably in underground geological formations for large period of time. It is then purified and monitored so that can be made to reuse. Monoethanolamine, zeolitic imidazolate framework, microalgae, membranes etc are utilized to capture CO2. Post-combustion, pre-combustion and oxyfuel combustion along with chemical looping combustion are technologies for scrubbing CO2. The properties of CO2 being easily miscible and readily dissolving in oil with impurities makes it capable for numerous applications such as in producing oil by enhanced oil recovery (EOR), Bio CCS Algal Synthesis etc. CO2-EOR operation is capable to produce million barrels of oil and extend the field's lifetime as in case of Weyburn Oil Field in Canada. The physical storage of CO2 is technically the most feasible direction provided that the associated safety and sustainability issues can be met and new materials for CCUS process at low cost are urgently found so that so that fossil based systems with carbon capture are cost competitive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title="carbon capture">carbon capture</a>, <a href="https://publications.waset.org/abstracts/search?q=CCUS" title=" CCUS"> CCUS</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil "> oil </a> </p> <a href="https://publications.waset.org/abstracts/20310/carbon-dioxide-capture-utilization-and-storage-sequestration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20310.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">519</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Accuracy and Depiction of Mental Illness-Popular Cinema</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Kapur">Ankur Kapur</a>, <a href="https://publications.waset.org/abstracts/search?q=Moosath%20Vasudevan"> Moosath Vasudevan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This movie review looks at the depiction of mental illness in popular cinema, using the movie A Beautiful Mind as a case study. It tries to understand cinema and media from a clinical psychology perspective in terms of the portrayal of symptoms and caregiver support. The review aims to analyze the portrayal of schizophrenia in the book and the movie ‘A Beautiful Mind’ on Professor John Nash. It will analyze the differences in portrayal of schizophrenia, under different media and the creative applications of the author, directors and actors in depicting the disorder as closely as it is understood in Clinical Psychology. The differences would be studied for romanticisation of symptoms in the book and the movie. Even within a medium (only the movie), verbal and non-verbal cues of the disorder will be compared for the depiction of schizophrenia. The study will dwell on the comparative description of how the caregivers coped with the patient and his illness. For this, the study will understand it through the lens of Bowen’s Family Systems Theory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=caregiver" title="caregiver">caregiver</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20theory" title=" systems theory"> systems theory</a> </p> <a href="https://publications.waset.org/abstracts/82780/accuracy-and-depiction-of-mental-illness-popular-cinema" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82780.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Seismic Data Scaling: Uncertainties, Potential and Applications in Workstation Interpretation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Mundhra">Ankur Mundhra</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubhadeep%20Chakraborty"> Shubhadeep Chakraborty</a>, <a href="https://publications.waset.org/abstracts/search?q=Y.%20R.%20Singh"> Y.

However, in dealing with data of different vintages, which perhaps were processed in 16 bits or even 8 bits and are need to be processed with 32 bit available data, scaling is performed. Also, scaling amplifies low amplitude events in deeper region which disappear due to high amplitude shallow events that saturate amplitude scale. We have focused on significance of scaling data to aid interpretation. This study elucidates a proper seismic loading procedure in workstations without using default preset parameters as available in most software suites. Differences and distribution of amplitude values at different depth for seismic data are probed in this exercise. Proper loading parameters are identified and associated steps are explained that needs to be taken care of while loading data. Finally, the exercise interprets the un-certainties which might arise when correlating scaled and unscaled versions of seismic data with synthetics. As, seismic well tie correlates the seismic reflection events with well markers, for our study it is used to identify regions which are enhanced and/or affected by scaling parameter(s). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clipping" title="clipping">clipping</a>, <a href="https://publications.waset.org/abstracts/search?q=compression" title=" compression"> compression</a>, <a href="https://publications.waset.org/abstracts/search?q=resolution" title=" resolution"> resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20scaling" title=" seismic scaling"> seismic scaling</a> </p> <a href="https://publications.waset.org/abstracts/24110/seismic-data-scaling-uncertainties-potential-and-applications-in-workstation-interpretation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24110.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Dispersion-Less All Reflective Split and Delay Unit for Ultrafast Metrology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akansha%20Tyagi">Akansha Tyagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehar%20S.%20Sidhu"> Mehar S.

It is based on symmetrical wavefront splitting of the measuring pulse having two separate arms to independently shape both split parts. We have validated our delay line with NIR –femtosecond pulse measurement centered at 800 nm using second harmonic-Interferometric frequency resolved optical gating (SH-IFROG). The delay line is compact, easy to align and provides attosecond stability and precision and thus make it more versatile for wide range of applications in ultrafast measurements.

During thin-film photocatalysis usually performed by a deposited layer of photocatalyst, a stagnant boundary layer is created near the catalyst which adversely affects the rate of adsorption because of diffusional restrictions. One strategy that may be used is to disrupt this laminar boundary layer by creating a super dense nanostructure near the surface of the catalyst. Further it is adequate to fabricate a structured filter element for a through pass of the water with as grown nanostructures coming out of the surface of such an element. So, the dye remediation is performed through solar means. This remediation was initially limited to lower efficiency because of diffusional restrictions but has now turned around as a fast process owing to the development of the filter materials with standing out dense nanostructures. The effect of increased surface area due to microholes on fraction adsorbed is also investigated and found that there is an optimum value of hole diameter for maximum adsorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20materials" title="nano materials">nano materials</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water%20treatment" title=" waste water treatment"> waste water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20remediation" title=" water remediation"> water remediation</a> </p> <a href="https://publications.waset.org/abstracts/33109/semiconducting-nanostructures-based-organic-pollutant-degradation-using-natural-sunlight-for-water-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33109.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Performance of Buildings with Base-Isolation System under Geometric Irregularities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firoz%20Alam%20Faroque">Firoz Alam Faroque</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Neog"> Ankur Neog</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earthquake causes significant loss of lives and severe damage to infrastructure. Base isolator is one of the most suitable solutions to make a building earthquake resistant. Base isolation consists of installing an isolator along with the steel plates covered with pads of strong material like steel, rubber, etc. In our study, we have used lead rubber bearing (LRB). The basic idea of seismic isolation is based on the reduction of the earthquake-induced inertia forces by shifting the fundamental period of the structure out of dangerous resonance range, and concentration of the deformation and energy dissipation demands at the isolation and energy dissipation systems, which are designed for this purpose. In this paper, RC frame buildings have been modeled and analyzed by response spectrum method using ETABS software. The LRB used in the model is designed as per uniform building code (UBC) 97. It is found that time period for the base isolated structures are higher than that of the fixed base structure and the value of base shear significantly reduces in the case of base-isolated buildings. It has also been found that buildings with vertical irregularities give better performance as compared to building with plan irregularities using base isolators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20isolation" title="base isolation">base isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20shear" title=" base shear"> base shear</a>, <a href="https://publications.waset.org/abstracts/search?q=irregularities%20in%20buildings" title=" irregularities in buildings"> irregularities in buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20rubber%20bearing%20%28LRB%29" title=" lead rubber bearing (LRB)"> lead rubber bearing (LRB)</a> </p> <a href="https://publications.waset.org/abstracts/67645/performance-of-buildings-with-base-isolation-system-under-geometric-irregularities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67645.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Uncertainty and Optimization Analysis Using PETREL RE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Sachan">Ankur Sachan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ability to make quick yet intelligent and value-added decisions to develop new fields has always been of great significance. In situations where the capital expenses and subsurface risk are high, carefully analyzing the inherent uncertainties in the reservoir and how they impact the predicted hydrocarbon accumulation and production becomes a daunting task. The problem is compounded in offshore environments, especially in the presence of heavy oils and disconnected sands where the margin for error is small. Uncertainty refers to the degree to which the data set may be in error or stray from the predicted values. To understand and quantify the uncertainties in reservoir model is important when estimating the reserves. Uncertainty parameters can be geophysical, geological, petrophysical etc. Identification of these parameters is necessary to carry out the uncertainty analysis. With so many uncertainties working at different scales, it becomes essential to have a consistent and efficient way of incorporating them into our analysis. Ranking the uncertainties based on their impact on reserves helps to prioritize/ guide future data gathering and uncertainty reduction efforts. Assigning probabilistic ranges to key uncertainties also enables the computation of probabilistic reserves. With this in mind, this paper, with the help the uncertainty and optimization process in petrel RE shows how the most influential uncertainties can be determined efficiently and how much impact so they have on the reservoir model thus helping in determining a cost effective and accurate model of the reservoir. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title="uncertainty">uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20model" title=" reservoir model"> reservoir model</a>, <a href="https://publications.waset.org/abstracts/search?q=parameters" title=" parameters"> parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20analysis" title=" optimization analysis"> optimization analysis</a> </p> <a href="https://publications.waset.org/abstracts/21057/uncertainty-and-optimization-analysis-using-petrel-re" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21057.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">652</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Service Life Modelling of Concrete Deterioration Due to Biogenic Sulphuric Acid (BSA) Attack-State-of-an-Art-Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Bansal">Ankur Bansal</a>, <a href="https://publications.waset.org/abstracts/search?q=Shashank%20Bishnoi"> Shashank Bishnoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Degradation of Sewage pipes, sewage pumping station and Sewage treatment plants(STP) is of major concern due to difficulty in their maintenance and the high cost of replacement. Most of these systems undergo degradation due to Biogenic sulphuric acid (BSA) attack. Since most of Waste water treatment system are underground, detection of this deterioration remains hidden. This paper presents a literature review, outlining the mechanism of this attack focusing on critical parameters of BSA attack, along with available models and software to predict the deterioration due to this attack. This paper critically examines the various steps and equation in various Models of BSA degradation, detail on assumptions and working of different softwares are also highlighted in this paper. The paper also focuses on the service life design technique available through various codes and method to integrate the servile life design with BSA degradation on concrete.

The current study reviews the surgical approaches used in the decompression of neurovascular structures and presents our reflections and recommendations. Methods: Four human cadavers, in the Department of Anatomy were used for dissection of the Axillae and the Scapular region by the senior residents of the Department of Anatomy and Department of Orthopedics, who dissected quadrangular space in the eight upper limbs, using anterior and posterior surgical approaches. Observations: Posterior approach to identify the quadrangular space and secure its contents was recognized as the easier and much quicker method by both the Anatomy and Orthopedic residents, but it may result in increased postoperative morbidity. Whereas the anterior (Delto-pectoral) approach involves more skill but reduces postoperative morbidity. Conclusions: Anterior (Delto-pectoral) approach with suggested modifications can prove as an effective method in surgical decompression of quadrangular space syndrome. The authors suggest more cadaveric studies to facilitate anatomists and surgeons with the opportunities to practice and evaluate older and newer surgical approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surgical%20approach" title="surgical approach">surgical approach</a>, <a href="https://publications.waset.org/abstracts/search?q=anatomical%20approach" title=" anatomical approach"> anatomical approach</a>, <a href="https://publications.waset.org/abstracts/search?q=decompression" title=" decompression"> decompression</a>, <a href="https://publications.waset.org/abstracts/search?q=axillary%20nerve" title=" axillary nerve"> axillary nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrangular%20space" title=" quadrangular space"> quadrangular space</a> </p> <a href="https://publications.waset.org/abstracts/142652/revisiting-the-surgical-approaches-to-decompression-in-quadrangular-space-syndrome-a-cadaveric-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142652.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Analysis of Impact of Air Pollution over Megacity Delhi Due to Agricultural Biomass Burning in the Neighbouring States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20P.%20Sati">Ankur P.

There are strong evidences that the Agricultural waste burning (AWB) in the Northern India leads to adverse air quality in Delhi and its surrounding regions. A severe smog episode was observed over Delhi, India during November 2012 which resulted in very low visibility and various respiratory problems. Very high values of pollutants (PM10 as high as 989 µg m-3, PM2.5 as high as 585 µg m-3 an NO2 as high as 540 µg m-3) were measured all over Delhi during the smog episode. Ultra Violet Aerosol Index (UVAI) from Aura satellite and Aerosol Optical Depth (AOD) are used in the present study along with the output trajectories from HYSPLIT model and the in-situ data. Satellite data also reveal that AOD, UVAI are always at its highest during the farmfires duration in Punjab region of India and the extent of these farmfires may be increasing. It is observed that during the smog episode all the AOD, UVAI, PM2.5 and PM10 values surpassed those of the Diwali period (one of the most polluted events in the city) by a considerable amount at all stations across Delhi. The parameters used from the remote sensing data and the ground based observations at various stations across Delhi are very well in agreement about the intensity of Smog episode. The analysis clearly shows that regional pollution can have greater contributions in deteriorating the air quality than the local under adverse meteorological conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smog" title="smog">smog</a>, <a href="https://publications.waset.org/abstracts/search?q=farmfires" title=" farmfires"> farmfires</a>, <a href="https://publications.waset.org/abstracts/search?q=AOD" title=" AOD"> AOD</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a> </p> <a href="https://publications.waset.org/abstracts/44106/analysis-of-impact-of-air-pollution-over-megacity-delhi-due-to-agricultural-biomass-burning-in-the-neighbouring-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> A Combination of Anisotropic Diffusion and Sobel Operator to Enhance the Performance of the Morphological Component Analysis for Automatic Crack Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Dixit">Ankur Dixit</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroaki%20Wagatsuma"> Hiroaki Wagatsuma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The crack detection on a concrete bridge is an important and constant task in civil engineering. Chronically, humans are checking the bridge for inspection of cracks to maintain the quality and reliability of bridge. But this process is very long and costly. To overcome such limitations, we have used a drone with a digital camera, which took some images of bridge deck and these images are processed by morphological component analysis (MCA). MCA technique is a very strong application of sparse coding and it explores the possibility of separation of images. In this paper, MCA has been used to decompose the image into coarse and fine components with the effectiveness of two dictionaries namely anisotropic diffusion and wavelet transform. An anisotropic diffusion is an adaptive smoothing process used to adjust diffusion coefficient by finding gray level and gradient as features. These cracks in image are enhanced by subtracting the diffused coarse image into the original image and the results are treated by Sobel edge detector and binary filtering to exhibit the cracks in a fine way. Our results demonstrated that proposed MCA framework using anisotropic diffusion followed by Sobel operator and binary filtering may contribute to an automation of crack detection even in open field sever conditions such as bridge decks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anisotropic%20diffusion" title="anisotropic diffusion">anisotropic diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=coarse%20component" title=" coarse component"> coarse component</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20component" title=" fine component"> fine component</a>, <a href="https://publications.waset.org/abstracts/search?q=MCA" title=" MCA"> MCA</a>, <a href="https://publications.waset.org/abstracts/search?q=Sobel%20edge%20detector%20and%20wavelet%20transform" title=" Sobel edge detector and wavelet transform"> Sobel edge detector and wavelet transform</a> </p> <a href="https://publications.waset.org/abstracts/90958/a-combination-of-anisotropic-diffusion-and-sobel-operator-to-enhance-the-performance-of-the-morphological-component-analysis-for-automatic-crack-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90958.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Seasonal Variation of the Unattached Fraction and Equilibrium Factor of ²²²Rn, ²²⁰Rn</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajan%20Jakhu">Rajan Jakhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Mehra"> Rohit Mehra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radon (²²²Rn) and its decay products are the major sources of natural radiation exposure to general population. The activity concentrations of radon, thoron gasses, and their unattached and attached short-lived progeny in indoor environment of the Jaipur and Ajmer districts of Rajasthan had been calculated via passive measurements using the Pinhole cup dosimeter, deposition based progeny sensors (DRPS/DTPS) and wire mesh capped (DRPS/DTPS) progeny sensors. The results of this study revealed that radon and thoron concentrations (CRn, CTn) are highest in the winter season. The variation of the radon and its decay products are observed to vary seasonally, but these environmental parameters seem not to be affecting the thoron and its decay product concentrations in a regular manner. The average values of the radon and its decay products are maximum in winter and minimum in summer. The equilibrium factor for radon is observed to be 0.50, 0.47 and 0.49 in winter, rainy and summer seasons. The annual average value of the unattached fraction of the radon progeny comes out to be 0.34. On the other hand, the average value of thoron (²²⁰Rn) concentration and its equilibrium factor in the studied area comes to be 74, 39, 45 Bq m⁻³ and 0.07, 0.11, 0.07 respectively for the winter, rainy and summer seasons with the annual average value of the unattached fraction of about 0.18. The annual average radiological dose from exposure to indoor radon and thoron progeny comes out to be 0.88 and 0.78 mSv. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equilibrium%20factor" title="equilibrium factor">equilibrium factor</a>, <a href="https://publications.waset.org/abstracts/search?q=radon" title=" radon"> radon</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20variation" title=" seasonal variation"> seasonal variation</a>, <a href="https://publications.waset.org/abstracts/search?q=thoron" title=" thoron"> thoron</a>, <a href="https://publications.waset.org/abstracts/search?q=unattached%20fraction" title=" unattached fraction"> unattached fraction</a> </p> <a href="https://publications.waset.org/abstracts/73360/seasonal-variation-of-the-unattached-fraction-and-equilibrium-factor-of-222rn-22rn" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73360.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Time Integrated Measurements of Radon and Thoron Progeny Concentration in Various Dwellings of Bathinda District of Punjab Using Deposition Based Progeny Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kirandeep%20Kaur">Kirandeep Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Mehra"> Rohit Mehra</a>, <a href="https://publications.waset.org/abstracts/search?q=Pargin%20Bangotra"> Pargin Bangotra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radon and thoron are pervasive radioactive gases and so are their progenies. The progenies of radon and thoron are present in the indoor atmosphere as attached/unattached fractions. In the present work, seasonal variation of concentration of attached and total (attached + unattached) nanosized decay products of indoor radon and thoron has been studied in the dwellings of Bathinda District of Punjab using Deposition based progeny sensors over long integrated times, which are independent of air turbulence. The preliminary results of these measurements are reported particularly regarding DTPS (Direct Thoron Progeny Sensor) and DRPS (Direct Radon Progeny Sensor) for the first time in Bathinda. It has been observed that there is a strong linear relationship in total EERC (Equilibrium Equivalent Radon Concentration) and EETC (Equilibrium Equivalent Thoron Concentration) in rainy season (R2 = 0.83). Further a strong linear relation between total indoor radon concentration and attached fraction has also been observed for the same rainy season (R2= 0.91).

So, for smart city development, a better traffic management and monitoring system is a very important requirement. Nowadays, road accidents increase due to more vehicles on the road. Reckless driving is mainly responsible for a huge number of accidents. So, an efficient traffic management system is required for all kinds of roads to control the traffic speed. The speed limit varies from road to road basis. Previously, there was a radar system but due to high cost and less precision, the radar system is unable to become favorable in a traffic management system. Traffic management system faces different types of problems every day and it has become a researchable topic on how to solve this problem. This paper proposed a computer vision and machine learning-based automated system for multiple vehicle detection, tracking, and speed estimation of vehicles using image processing. Detection of vehicles and estimating their speed from a real-time video is tough work to do. The objective of this paper is to detect vehicles and estimate their speed as accurately as possible. So for this, a real-time video is first captured, then the frames are extracted from that video, then from that frames, the vehicles are detected, and thereafter, the tracking of vehicles starts, and finally, the speed of the moving vehicles is estimated. The goal of this method is to develop a cost-friendly system that can able to detect multiple types of vehicles at the same time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OpenCV" title="OpenCV">OpenCV</a>, <a href="https://publications.waset.org/abstracts/search?q=Haar%20Cascade%20classifier" title=" Haar Cascade classifier"> Haar Cascade classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=DLIB" title=" DLIB"> DLIB</a>, <a href="https://publications.waset.org/abstracts/search?q=YOLOV3" title=" YOLOV3"> YOLOV3</a>, <a href="https://publications.waset.org/abstracts/search?q=centroid%20tracker" title=" centroid tracker"> centroid tracker</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20detection" title=" vehicle detection"> vehicle detection</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20tracking" title=" vehicle tracking"> vehicle tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20speed%20estimation" title=" vehicle speed estimation"> vehicle speed estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a> </p> <a href="https://publications.waset.org/abstracts/153549/vehicle-speed-estimation-using-image-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Short-Term Impact of a Return to Conventional Tillage on Soil Microbial Attributes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Promil%20Mehra">Promil Mehra</a>, <a href="https://publications.waset.org/abstracts/search?q=Nanthi%20Bolan"> Nanthi Bolan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jack%20Desbiolles"> Jack Desbiolles</a>, <a href="https://publications.waset.org/abstracts/search?q=Risha%20Gupta"> Risha Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agricultural practices affect the soil physical and chemical properties, which in turn influence the soil microorganisms as a function of the soil biological environment. On the return to conventional tillage (CT) from continuing no-till (NT) cropping system, a very little information is available from the impact caused by the intermittent tillage on the soil biochemical properties from a short-term (2-year) study period. Therefore, the contribution made by different microorganisms (fungal, bacteria) was also investigated in order to find out the effective changes in the soil microbial activity under a South Australian dryland faring system. This study was conducted to understand the impact of microbial dynamics on the soil organic carbon (SOC) under NT and CT systems when treated with different levels of mulching (0, 2.5 and 5 t/ha). Our results demonstrated that from the incubation experiment the cumulative CO2 emitted from CT system was 34.5% higher than NT system. Relatively, the respiration from surface layer (0-10 cm) was significantly (P<0.05) higher by 8.5% and 15.8 from CT; 8% and 18.9% from NT system w.r.t 10-20 and 20-30 cm respectively. Further, the dehydrogenase enzyme activity (DHA) and microbial biomass carbon (MBC) were both significantly lower (P<0.05) under CT, i.e., 7.4%, 7.2%, 6.0% (DHA) and 19.7%, 15.7%, 4% (MBC) across the different mulching levels (0, 2.5, 5 t/ha) respectively. In general, it was found that from both the tillage system the enzyme activity and MBC decreased with the increase in depth (0-10, 10-20 and 20-30 cm) and with the increase in mulching rate (0, 2.5 and 5 t/ha). From the perspective of microbial stress, there was 28.6% higher stress under CT system compared to NT system. Whereas, the microbial activity of different microorganisms like fungal and bacterial activities were determined by substrate-induced inhibition respiration using antibiotics like cycloheximide (16 mg/gm of soil) and streptomycin sulphate (14 mg/gm of soil), by trapping the CO2 using an alkali (0.5 M NaOH) solution. The microbial activities were confirmed through platting technique, where it was that found bacterial activities were 46.2% and 38.9% higher than fungal activity under CT and NT system. In conclusion, it was expected that changes in the relative abundance and activity of different microorganisms (bacteria and fungi) under different tillage systems could significantly affect the C cycling and storage due to its unique structures and differential interactions with the soil physical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tillage" title="tillage">tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20respiration" title=" soil respiration"> soil respiration</a>, <a href="https://publications.waset.org/abstracts/search?q=MBC" title=" MBC"> MBC</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal-bacterial%20activity" title=" fungal-bacterial activity"> fungal-bacterial activity</a> </p> <a href="https://publications.waset.org/abstracts/61041/short-term-impact-of-a-return-to-conventional-tillage-on-soil-microbial-attributes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61041.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> A Theoretical Approach on Electoral Competition, Lobby Formation and Equilibrium Policy Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepti%20Kohli">Deepti Kohli</a>, <a href="https://publications.waset.org/abstracts/search?q=Meeta%20Keswani%20Mehra"> Meeta Keswani Mehra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper develops a theoretical model of electoral competition with purely opportunistic candidates and a uni-dimensional policy using the probability voting approach while focusing on the aspect of lobby formation to analyze the inherent complex interactions between centripetal and centrifugal forces and their effects on equilibrium policy platforms. There exist three types of agents, namely, Left-wing, Moderate and Right-wing who comprise of the total voting population. Also, it is assumed that the Left and Right agents are free to initiate a lobby of their choice. If initiated, these lobbies generate donations which in turn can be contributed to one (or both) electoral candidates in order to influence them to implement the lobby’s preferred policy. Four different lobby formation scenarios have been considered: no lobby formation, only Left, only Right and both Left and Right. The equilibrium policy platforms, amount of individual donations by agents to their respective lobbies and the contributions offered to the electoral candidates have been solved for under each of the above four cases. Since it is assumed that the agents cannot coordinate each other’s actions during the lobby formation stage, there exists a probability with which a lobby would be formed, which is also solved for in the model. The results indicate that the policy platforms of the two electoral candidates converge completely under the cases of no lobby and both (extreme) formations but diverge under the cases of only one (Left or Right) lobby formation. This is because in the case of no lobby being formed, only the centripetal forces (emerging from the election-winning aspect) are present while in the case of both extreme (Left-wing and Right-wing) lobbies being formed, centrifugal forces (emerging from the lobby formation aspect) also arise but cancel each other out, again resulting in a pure policy convergence phenomenon. In contrast, in case of only one lobby being formed, both centripetal and centrifugal forces interact strategically, leading the two electoral candidates to choose completely different policy platforms in equilibrium. Additionally, it is found that in equilibrium, while the donation by a specific agent type increases with the formation of both lobbies in comparison to when only one lobby is formed, the probability of implementation of the policy being advocated by that lobby group falls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electoral%20competition" title="electoral competition">electoral competition</a>, <a href="https://publications.waset.org/abstracts/search?q=equilibrium%20policy%20platforms" title=" equilibrium policy platforms"> equilibrium policy platforms</a>, <a href="https://publications.waset.org/abstracts/search?q=lobby%20formation" title=" lobby formation"> lobby formation</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunistic%20candidates" title=" opportunistic candidates"> opportunistic candidates</a> </p> <a href="https://publications.waset.org/abstracts/81499/a-theoretical-approach-on-electoral-competition-lobby-formation-and-equilibrium-policy-platforms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81499.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Spatio-Temporal Analysis of Land Use Change and Green Cover Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Poonam%20Sharma">Poonam Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Srivastav"> Ankur Srivastav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cities are complex and dynamic systems that constitute a significant challenge to urban planning.

Urban environmental quality is influenced by several aspects, including its geographical configuration, the scale, and nature of human activities occurring and environmental impacts generated. Cities have transformed into complex and dynamic systems that constitute a significant challenge to urban planning. Cities and their sustainability are often discussed together as the cities stand confronted with numerous environmental concerns as the world becoming increasingly urbanized, and the cities are situated in the mesh of global networks in multiple senses. A rapid transformed urban setting plays a crucial role to change the green area of natural habitats. To examine the pattern of urban growth and to measure the Landuse/Landcover change in Gurgoan in Haryana, India through the integration of Geospatial technique is attempted in the research paper. Satellite images are used to measure the spatiotemporal changes that have occurred in the land use and land cover resulting into a new cityscape. It has been observed from the analysis that drastically evident changes in land use has occurred with the massive rise in built up areas and the decrease in green cover and therefore causing the sustainability of the city an important area of concern. The massive increase in built-up area has influenced the localised temperatures and heat concentration. To enhance the decision-making process in urban planning, a detailed and real world depiction of these urban spaces is the need of the hour. Monitoring indicators of key processes in land use and economic development are essential for evaluating policy measures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cityscape" title="cityscape">cityscape</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20techniques" title=" geospatial techniques"> geospatial techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20cover%20index" title=" green cover index"> green cover index</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20environmental%20quality" title=" urban environmental quality"> urban environmental quality</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20planning" title=" urban planning"> urban planning</a> </p> <a href="https://publications.waset.org/abstracts/65946/spatio-temporal-analysis-of-land-use-change-and-green-cover-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Compensation of Bulk Charge Carriers in Bismuth Based Topological Insulators via Swift Heavy Ion Irradiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyoti%20Yadav">Jyoti Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Rini%20Singh"> Rini Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anoop%20%20M.D"> Anoop M.D</a>, <a href="https://publications.waset.org/abstracts/search?q=Nisha%20%20Yadav"> Nisha Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20Srinivasa%20Rao"> N.

Defects and strain affect the physical as well as topological insulating properties of the Bi2Te3 thin films by changing their electronic structure. In the present studies, the effect of Ni7+ ion irradiation on the physical and electrical properties of Bi2Te3 thin films was studied. The films were irradiated at five different fluences (5x1011, 1x1012, 3x1012, 5x1012, 1x1013 ions/cm2). Thin films synthesized using the e-beam technique possess a rhombohedral crystal structure with the R-3m space group. The average crystallite size, as determined by x-ray diffraction (XRD) peak broadening, was found to be 18.5 ± 5 (nm). It was also observed that irradiation increases the induced strain. Raman Spectra of the films demonstrate the splitting of A_1u^1 modes originating from the vibrations along the c-axis. This is by the variation in the lattice parameter ‘c,’ as observed through XRD. The atomic force microscopy study indicates the decrease in surface roughness up to the fluence of 3x1012 ions/cm2 and further increasing the fluence increases the roughness. The decrease in roughness may be due to the growth of smaller nano-crystallites on the surface of thin films due to irradiation-induced annealing. X-ray photoelectron spectroscopy studies reveal the composition to be in close agreement to the nominal values i.e. Bi2Te3. The resistivity v/s temperature measurements revealed an increase in resistivity up to the fluence 3x1012 ions/cm2 and a decrease on further increasing the fluence. The variation in electrical resistivity is corroborated with the change in the carrier concentration as studied through low-temperature Hall measurements. A crossover from the n-type to p-type carriers was achieved in the irradiated films. Interestingly, tuning of the Fermi level by compensating the bulk carriers using ion-irradiation could be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Annealing" title="Annealing">Annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=Irradiation" title=" Irradiation"> Irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=Fermi%20level" title=" Fermi level"> Fermi level</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuning" title=" Tuning"> Tuning</a> </p> <a href="https://publications.waset.org/abstracts/122719/compensation-of-bulk-charge-carriers-in-bismuth-based-topological-insulators-via-swift-heavy-ion-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122719.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Prognosis of Patients with COVID-19 and Hematologic Malignancies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20%20Behrens">Elizabeth Behrens</a>, <a href="https://publications.waset.org/abstracts/search?q=Anne%20Timmermann"> Anne Timmermann</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Yerkan"> Alexander Yerkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Thomas"> Joshua Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Deborah%20Katz"> Deborah Katz</a>, <a href="https://publications.waset.org/abstracts/search?q=Agne%20Paner"> Agne Paner</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Larson"> Melissa Larson</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivi%20Jain"> Shivi Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Seo-Hyun%20Kim"> Seo-Hyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Celalettin%20Ustun"> Celalettin Ustun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Varma"> Ankur Varma</a>, <a href="https://publications.waset.org/abstracts/search?q=Parameswaran%20Venugopal"> Parameswaran Venugopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamile%20Shammo"> Jamile Shammo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coronavirus Disease-2019 (COVID-19) causes persistent concern for poor outcomes in vulnerable populations. Patients with hematologic malignancies (HM) have been found to have higher COVID-19 case fatality rates compared to those without malignancy. While cytopenias are common in patients with HM, especially in those undergoing chemotherapy treatment, hemoglobin (Hgb) and platelet count have not yet been studied, to our best knowledge, as potential prognostic indicators for patients with HM and COVID-19. The goal of this study is to identify factors that may increase the risk of mortality in patients with HM and COVID-19. In this single-center, retrospective, observational study, 65 patients with HM and laboratory confirmed COVID-19 were identified between March 2020 and January 2021. Information on demographics, laboratory data the day of COVID-19 diagnosis, and prognosis was extracted from the electronic medical record (EMR), chart reviewed, and analyzed using the statistical software SAS version 9.4. Chi-square testing was used for categorical variable analyses. Risk factors associated with mortality were established by logistic regression models. Non-Hodgkin lymphoma (37%), chronic lymphocytic leukemia (20%), and plasma cell dyscrasia (15%) were the most common HM. Higher Hgb level upon COVID-19 diagnosis was related to decreased mortality, odd ratio=0.704 (95% confidence interval [CI]: 0.511-0.969; P = .0263). Platelet count the day of COVID-19 diagnosis was lower in patients who ultimately died (mean 127 ± 72K/uL, n=10) compared to patients who survived (mean 197 ±92K/uL, n=55) (P=.0258). Female sex was related to decreased mortality, odd ratio=0.143 (95% confidence interval [CI]: 0.026-0.785; P = .0353). There was no mortality difference between the patients who were on treatment for HM the day of COVID-19 diagnosis compared to those who were not (P=1.000). Lower Hgb and male sex are independent risk factors associated with increased mortality of HM patients with COVID-19. Clinicians should be especially attentive to patients with HM and COVID-19 who present with cytopenias. Larger multi-center studies are urgently needed to further investigate the impact of anemia, thrombocytopenia, and demographics on outcomes of patients with hematologic malignancies diagnosed with COVID-19. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anemia" title="anemia">anemia</a>, <a
